I've just bought a second hand Marshall 9005 50/50 power amp. It is a dual mono block amp (two seperate 50 watt amps for channel A and B). Razorjack mentioned that running it at full power (not using the half power switch) in stereo would be the way to get the best sound out of it. I'm using a POD XT LIVE into the 9005 into my home made 2X12 cab. The cab has 2, 75 watt Celestion GT12-75 (8ohm) speakers running at 4ohms together. My cab only has one input jack however as I made it to use with my one output Fender Bassman 100. I assume that I should take one lead each out of the right and left output of the POD into each channel of the 9005 (POD LEFT into Channel A and POD RIGHT into Channel B). But to use both channel's outputs do I need a stereo 4X12 with two inputs or can I change my 2X12 to accept two inputs (one for each speaker and run the 9005 at 8 ohms on each channel? Hope I didn't over complicate this lol Any help is greatly appreciated.
